Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...

On paper, LED bulbs are made to last for at least several years thanks to their low energy needs. I wanted to know why that doesn't always work out, so I talked to installers and LED manufacturers to ...

Chris Wedel is a fan of all things tech and gadgets. Living in rural Kansas with his wife and two young boys makes finding ways to stay online tricky — not to mention making my homestead smarter.

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

This project simulates an LED matrix display on your computer screen. Think of it like a grid of tiny lights (LEDs) that you can control individually - just like those scrolling LED signs you see in ...

Project Description This project uses YOLOv8 for object detection and an Arduino Uno (or Mega) to control an LED. If an electronic device is detected in the camera feed, the LED glows. The system ...

Abstract: As the activeness of most species and plants depends on illumination and brightness of the Sun, sun cells a efficient during day. Moreover, the solar arrays cost less if they operate at ...

A new New York law mandates mental health warning labels on addictive social media features, allowing state enforcement and reflecting growing global concern over youth online safety.
